I'm having issues with IE11 as well. websites like msn.com, espn.com and even wpcentral.com are having some issues on IE11. In msn.com the news tiles scroll left and right just fine, but if I click on any of them nothing happens and it doesn't take me to the news article. Oddly enough, the blue tiles (skype, twitter, weather, etc.) work just fine. In espn.com, when I click on a video, the video does not plays but the sounds does. In wpcentral.com my issues start when I enter the forums (weird, maybe it is a sign

). When I go into the forums, it takes a while to load and often closes the tab and opens a new blank tab or the browser just crashes. So there are my first world issues so far with wp8.1
edit: Now msn.com is working fine. Still having the the video problem with espn.com and the crashes with the wpcentral.com forums.
